Change in Mini Mental Status Exam (MMSE) score one hour after the end of anesthesia, numbers indicate median, 95% confidence interval. Although the MMSE score decreased more in the 47 patients anesthetized with sevoflurane (−2.4, −3.2 to −1.7) than in the 37 patients anesthetized with desflurane (−1.3; −2.3 to −0.5; p = 0.04 Wilcoxon), the difference in the magnitude of decrease was not clinically significant (not at least 2 points).
